Scar,
IMO I think that cats usually are linked to calmer people (Also elder women and the unemployed

). Usually modelers are calm thorough people who wont mind spending 10+ hrs in the shop just trimming balsa sheeting on a custom cowling. This way I figured that maybe modelers where more prone to be cat people. I'm certainly one of them. Nothing against dogs, I like them too. I just don't care for dog smell.
